SpaceX Falcon 9 Block 5 ready to launch second largest communications satellite

Falcon 9’s liftoff is scheduled tonight, 11:38 PM EDT/03:38 UTC

After a long slip and slide from mid-August to September 9th, SpaceX and customer Telesat Canada are ready to launch the second largest communications satellite to a geostationary transfer orbit, Telstar 18V, following in the footsteps of a July 2018 launch of the slightly heavier (~15 kg) Telstar 19V satellite.

We’re a couple of hours from launch of Telstar 18V. This was captured tonight during remote camera setup. Stormy skies here on the space coast but appear to be clearing prior to launch. We have a 4-hour window if needed@Teslarati #spacex @spacex @elonmusk pic.twitter.com/IlqqCVeI5q

Originally expected to occur as little as a month after Telstar 19V (launched July 22nd), Telstar 18V experienced a number of somewhat mysterious slips, moving from the third week of August to the end of August, then slipping again from September 8th to September 9th, today. Publicly, it’s entirely unclear what caused that unusual three-week delay, but the obvious answers revolve around some combination of multiple problems with the launch pad (LC-40, Cape Canaveral Air Force Station), rocket (B1049, a new Falcon 9 Block 5 vehicle), payload (a vast, 7060-kilogram spacecraft), and more.

Ultimately, there is simply a lot that can go wrong with the rocket itself and the vast swath of infrastructure that must work near-flawlessly, in concert, if a launch is to even be attempted, let alone be completed successfully. It may be rather frustrating as a follower (or raving addict) of rocket launches and SpaceX in particular, but it never hurts to remember that being able to watch an official livestream at all is an absolute privilege and not something that SpaceX or any other rocket company is required to provide. The purpose of SpaceX’s present-day business is business, after all, and successfully placing customer payloads (be that customer NASA, the USAF, or a commercial entity like Telesat) is the name of that game – quite literally everything after that comes in a firm second place.
